Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides, when any switching equipment or line concentrator in a switching network goes down, a remote location that is not adjacent to the equipment where the system is down. The present invention relates to a remote program initialization method in which a network control device (or a switching device having the same function as a network control device) initializes a necessary program file for a device whose system is down.

[Conventional technology]

Conventionally, when a switching device or concentrator (hereinafter referred to as a target station) whose system is in an idle state (a) (system down) due to a system failure or construction work, a switch is sent from another switching device or network management device installed at another location. The following methods were used to initialize the required programs.

The conventional method shown in FIG. 3 connects the target stations 21 to 2N to which the required program files are to be initialized and the switching devices ff111 to IM having the function of transferring the program files to the inter-station IL%'131 to 3N, 3L. This example shows how to connect directly to the program file and set the program file accordingly.

The method shown in FIG. 4 is a method for initializing a program file when the control device 5 having a program file initialization function and the target stations 21 to 2N under the control device are directly connected via a dedicated line 41^4P. It shows.

Note that 31.3L is an interoffice line.

The operation of program file initialization can be logicalized as shown in the operation explanatory diagram of FIG. 5 in either method. In FIG. 5, 1 is an exchange device or a control device having a program initialization function, 2 is an exchange device or a concentrator, that is, a target station, for program file initialization, 3 is an inter-office line, 112 is an input/output device, 111 211 is a conversion transfer block, 211 is a line corresponding section, and 212 is a memory.

If the program processing at target station 2 is suspended due to construction or a failure, it is necessary to initialize the program file and restart the target station, but since the program is not running, complicated procedures are not possible. If the program cannot be transferred, the line support unit 211 is equipped with a function of reading a specific pidpakun by hardware operation and setting the program on the memory 212, and the program file is transferred to the directly connected inter-office line 3. In other words, it was transferring.

When initializing the program file for target station 2, the program file is the first! The switching device or control device 1 having the tII setting function reads the program file to be initialized from the input/output device 112 and uses the function block 111 for transferring the program file to transfer the read program file to the line support unit 211 of the destination station 2. The data unit structure and procedure are converted into a data unit structure and procedure that can be decoded, and the data is transferred using an inter-office line 3 directly connected to the destination station 2.

[Problem that the invention seeks to solve]

The wooden sword type allows initial settings to be made by transferring program files from a remote location, but the disadvantage is that the target station must have an inter-office line to connect to the switching equipment on the controlling side, making it uneconomical. there were.

An object of the present invention is to solve these drawbacks and provide an economical remote program initialization method that does not require an interoffice line connecting the target station to the switching equipment it controls. There is a particular thing.

[Means for solving problems]

To achieve the above object, the present invention provides an exchange having the function of converting a data unit transferred from a network control device within a network into a format and signal procedure that can be decoded by a remote device serving as a destination station. The device was provided as an intermediate control device.

[Effect]

In the present invention, a direct inter-office line is provided to each exchange or each concentrator in the network, and this exchange or #JvA
Instead of directly downloading the program file when the system goes down, the program file that should be set in the exchange or concentrator W (destination station) whose system is down is downloaded to each switching equipment in the switching network. The routing function transfers the data units in appropriate units (data units) to the switching equipment (intermediate control device) adjacent to the destination station, and the intermediate control device rearranges the data units in the correct order and formats the data units in a format that the destination station can decipher. and procedure, connect it to the inter-station line that connects directly to the target station, download the program file to the target station, and restart the target station. This allows the number of lines for program file transfer to be reduced.

〔Example〕

FIG. 1 is a configuration diagram showing an embodiment of the present invention, and FIG. 2 is an explanatory diagram of its internal operation. Referring to these figures, the network control device l, which has the function of transferring program files, divides the program file to be initialized into appropriate units (data units), and transfers these data units via the exchange network. The operation of sending the data to the destinations 21 to 2N and initializing the program file will be explained.

In FIG. 1, 51-5Q are adjacent to the destinations 21-2N and convert the data units transferred from the network controller 1 into a format and signal procedure that the destinations 21-2N as remote devices can decipher. This is an exchange device that has a conversion function. This is called an intermediate control device. 61 to 6R are exchange devices that are not interpurpose or intermediate control devices for which program files should be initialized, and have a routing function. 71 to 7S are inter-office lines that directly connect the intermediate control devices 51 to 5Q and the destinations 21 to 2N, and the intermediate control devices 51 to 5 that control the destinations 21 to 2N and the destinations 21 to 2N.
It is assumed that the network control device 1 knows the combination with Q.

That is, in the event that the system of the exchange or line concentrator between the destinations goes down, the network control device 1 knows which neighboring station should be used as an intermediate control device to transfer the program file. Reference numeral 8 denotes an inter-office line other than the direct inter-office lines 71 to 7S between the objects and the intermediate control device.

In FIG. 2, 91 is the format of a data unit for transferring a program file between a network control device and an intermediate control device, and it includes information and a sequence number for performing routing control according to a transfer procedure 901 within a switching network. It consists of a header section 911 including a program file storage section 912 and a program file storage section 912 divided into data lengths that can be transferred within the network.

Depending on the procedure within the switched network, it is possible to use a transfer procedure according to CCITT Recommendation X, 25 or a routing procedure specifically defined within the switched network. The data units are aligned in order by intermediate controllers 71-7S. 92 is a format that is sent and received between an intermediate control device and a target, and is used to start up the hardware between the targets when the system is inactive and set a program file between the targets, and to set a program between the targets and restart the system. The data unit transfer control procedure between the intermediate control device and the target device is 902.

In this embodiment, a remote program initialization method for initializing a program file from the network control device 1 to the destination 21 when the system is inactive will be described.

As already mentioned, Fig. 2 is for explaining this operation.
When setting the program file to the destination 21, the network control device 1. Exchange device 61. Intermediate control device 51. and shows the internal operation of the inter-purpose unit 21. 112 is an input/output device for reading the program file, 111 is a data unit transfer function block for dividing the read program file into appropriate units (data units) and transferring it within the network, and 8 is an inter-office line. . 611 is a functional block that relays and routes received data units, and 511 is a functional block that receives data units from the interoffice line 8.

512 indicates that when the data unit received by the function block 511 is for initializing the purpose 21,
This is a procedure conversion and transfer function block that converts the data unit into a format 92 and a procedure 902 that can be decoded by the hardware in the destination 21 while the system is inactive and transfers it. 71
is an interoffice line that directly connects the intermediate control device 51 and the destination 21, and the network control device 1 and the intermediate control device 51 recognize in advance this interoffice line 71 to be used. Reference numeral 211 denotes a line correspondence unit having the function of decoding the data unit that has passed through the interoffice line 71, storing it in the memory 212, and starting up the system between the interoffices 21.

Next, the operation will be explained step by step.

When initializing a program file due to a system failure or construction work, the network control device 1 reads the program file to be initialized from the input/output device 112 and transfers the program by the operation of the data unit transfer control function block 111. The file is divided and stored in the program file storage part 911 of the data unit, and information including routing information and sequence numbers is put in the header part 912, converted into the format 91, and according to the intra-network transfer procedure 901, the The data is sent to the intermediate line 8.

The data unit 91 is routed to the intermediate control device 51 through the routing function block 611 of the switching device 61 .

The intermediate control device 51 receives the data unit 91, and the data unit receiving function block 511 determines that the data unit 91 is addressed to the intermediate control device 51 and is a data unit for initializing a program file to the destination 21. When recognized, the procedure conversion transfer function block 512 converts the format 91 transferred in the intra-network transfer procedure 901 into a focus pattern 921 and a program file portion 922 that can be decoded by the line support unit 211 of the destination 21 during system suspension. The data unit of format 92 is converted into the combined format 92, and the data unit of format 92 is transferred through the direct inter-office line 71 according to the data unit transfer procedure 902.

The line correspondence unit 211 of the destination 21 receives the data unit (9
2) is stored in the memory 212, and when it is recognized that the transfer of the program file has been completed, the system is started up.

Within the switching network, combinations of inter-purpose and intermediate control devices can be arbitrarily determined. In other words, there is a function as an inter-object that can receive a specific data unit by hardware operation and restart the system, and a function that converts the data unit received from the network control device in order control nine steps, converts the format, and initializes the program file for the inter-object. The functions to be set can be set arbitrarily to each switching device within the network.

This is necessary to initialize a certain intermediate control device when it becomes a failure. In other words, a higher-level intermediate control bag for that intermediate control device determines in advance the exchange device that has the role of If the control device has it, it is possible to initialize the program file. By applying this relationship to all network devices, it is possible to initialize program files for all network devices.

Note that the inter-objective can serve as an intermediate control device that intermediately controls other inter-objectives during a period other than the initial setting period of the inter-objective itself, that is, while it is in normal operation.

〔Effect of the invention〕

As explained above, in a switching network, a program file is transferred from a network control device or a switching device with a remote control function using the routing function of the switching device within the switching network, and initialization of the program file at a remote location is performed. The switching equipment adjacent to the target switching equipment or line concentrator converts the format of the data unit transferred within the network into a format and signaling system that can operate the hardware of the network equipment to be initialized. It becomes possible to set the program file of the device, and has the advantage that lines can be used more effectively than conventional methods.
